What was the experience of scientists looking at galaxies up close?

Monday, September 20, 2021

Astronomers have experimented with taking pictures of galaxies in space at 'ultra-high definition resolutions. These images of galaxies are the most detailed and up-to-date images ever taken, giving a very close look at the compounds of galaxies.

Many of these images provide information about the structure of stars and planets and the black holes in them. Researchers say that these images will be very helpful in understanding the evolution of galaxies and the factors behind their formation. These images are of radio waves emanating from these galaxies.


Researchers often study galaxies' radio waves instead of visible light because they enable them to see things that would otherwise not be visible in distant galaxies due to the Earth's atmosphere or dust and gas. ۔


Many areas of space are hidden from our eyes or appear dark to us. These technologies help astronomers observe the formation of planets in the depths of space and the center of galaxies. This time the team of astronomers has done a new job to get the most prominent and detailed images of the galaxies by connecting more than 70,000 small radio waves antennas installed in nine European countries The resolution of the images has increased dramatically.


But combining the signals of so many radio antennas was not an easy task. For six years, a team of astronomers set up a system that took signals from each antenna, digitized them, and then transmitted them to the system's main processor. Combining all this data was not only a very important scientific experiment, but the results were fascinating and fascinating. The team that achieved this technical success was led by Dr. Leah Morobito of Durham University, UK.


"It was great to work on this data for so long and finally get the most detailed and beautiful images and be the first person to know what it all looks like," he told BBC News. "I had a big smile on my face all the time that day because I was so proud that I was able to get these pictures and see what no one has seen before today," he said.


An image of the galaxies obtained at the top of this article, obtained by a member of Dr. Morabito's team, shows barely a galaxy with two orange jets that look like clouds of smoke from jets. The color is visible from the middle of the astronomical material. These two parts are larger than the galaxy.


These materials are created by a very large black hole in the center of the galaxy, an object that has so much gravity that even light cannot pass through. It usually attracts matter, but internal tensions also create forces around the black hole, causing the material to travel far into space.


Astronomers have seen such material before, but now they say they have done new scientific research about it that has never been seen before. Astronomers say the material in the image indicates that the galaxy's black hole has been inactive for some time because it has sent very little material into space.


So this image provides researchers with information about the black hole's 'sleep cycle'.

The image above shows the two galaxies colliding, the bright part shining on the right causing the stars to explode, creating an efficient galacton wind that blows away gas and dust. The light visible just above this galaxy was created when the universe was 2.6 billion years old. Above and below it is the jet material spread by the black hole.


Normally it was not possible to examine such old and distant galaxies in detail, but now for the first time astronomers have tried to find out the identity of one of them through radio frequency which is important information about it. Provides what effect a black hole in space is having around us.

According to Dr. Neil Jackson of the University of Manchester, the images show that galaxies are more than just clusters of stars. These are huge solar and planetary factories powered by black holes. "Experienced astronomers will be amazed when they see these images," he told me.


"To understand the evolution of the galaxy, it has become very clear, we have to understand the center inside the black hole, because it appears to have a significant effect on the evolution of galaxies," says Dr. Jackson. Pictures will help us do that.


"These high-resolution images will help us to know and even see what happens when these large black holes throw jet material into space," he said.


Dr. Morabito says such images are helping astronomers understand the process and are trying to figure out how stars and planets, including our solar system, come into being. "We are beginning to understand how galaxies are formed and black holes are an important part of them because their extracted jet material helps create stars," he said. And when they push it out, it shakes the galaxies. They can even trigger or extinguish the formation of stars and reduce it.


In light of these findings, nine scientific research papers have been written on the massive black holes in galaxies, but this is only the beginning for the team. He plans to study millions of galaxies in space over the next few years.


"We will be able to find out what effect black holes have on the formation of galaxies," said Dr. Moabito. "I think we're going to have more amazing discoveries. Whenever you start doing something new in the world of astronomy, you get something unexpected, and I hope something like that," she says. ۔ '


This international network of telescopes is called the low-frequency array or 'loafer'. Most of these antenna axles are in the Netherlands.
